Actual speed about 10 MB/s or 10 mega bytes per second. looks more like a half-breed, something between 5 MB/s and a dead dog, I had initially envisaged moving 2tb image files :-)))) will have to work down my expectations, or as eastwood would say:
Lot's of things can affect your transfer bandwidths. I just tried a quick test sending a 4-GB file between two recent SuperMicro servers over a 40GbE Ethernet connection. It's a copper connection directly between the two servers, no switches or routers in the way. So I got 467.2MB/s for a 4GB binary file sent using scp. If you do the math that would be about 45-minutes to transfer 1TB. But realize that scp encrypts the data going over the link. Last year I tried some bandwidth tests and managed to speed the transfers up by a factor of 2.5 or so with encryption turned off. One doesn't need it when sending data between computers in the same equipment rack! Unfortunately it isn't easy to turn off scp encryption, you need to install rcp and munge. I had it working under Leap 42, but not under any of the 15.x releases. I didn't try to hard though. Regards, Lew
